Another principle was that universal one of sacrifices for expiation, and rendering God propitious to man, and was practised among all nations. I remember not any wherein this custom did not prevail; for it did even among those people where the Jews, as being no trading nation, had not any commerce; and also in America, found out in these latter ages. It was not a law of nature; no man can find any such thing written in his own heart, but a tradition from Adam. Now that among the loss of so many other doctrines that were handed down from Adam to his immediate posterity, as, in particular, that of the Seed of the woman, which one would think a necessary appendix to that of sacrificing, this latter should be preserved as a fragment of an ancient tradition, seems to be an act of Divine wisdom to prepare men for the entertainment of the doctrine of the great Sacrifice for the expiation of the sin of the world. And as the apostle forms his argument from the Jewish sacrifices, in the epistle to the Hebrews, for the convincing them of the end of the death of Christ, so did the ancient fathers make use of this practice of the heathen to convince them of the same doctrine.
